Answer 2

We have, C.P. of the toy =Rs250 and S.P. of the toy = Rs285

Since S.P. > C.P .So, there is profit/gain given by:

$$Profit = S.P. – C.P.\\ Profit = Rs.285 – Rs.250\\ Profit = Rs.35$$

Now lets calculate gain in percentange:

$$Profit\; \%=\left( \frac { Profit }{ C.P. } \right) \times 100\\ Profit\; \%=\left( \frac { 35 }{ 250. } \right) \times 100\%\\ Profit\; \ %\quad =14 \%$$

Hence, Gain = Rs 35 and Gain% =14
